Spark Plug - KYMCO 50 Owner's Manual

MAINTENANCE

Spark plug

Remove the carbon deposits from the spark plug with a small
wire brush, a pick 1 or a spark plug cleaning machine. After
cleaning (or when installing a new spark plug) readjust the
spark plug gap 2 to the specified limit by using a spark plug
gap thickness gauge. The spark plug should also be replaced
if the sealing washer 3 has been compressed flat from mul-
tiple installations. The spark plug should be replaced periodi-
cally. Under normal usage, a spark plug's porcelain tip 4
should appear light brown or tan in color. If the spark plug por-
celain tip is very white or glazed appearing, then the spark
plug has been operating too hot. In such a situation, you should
replace the standard spark plug with a spark plug that has a
colder heat range (usually a higher number; consult with your
KYMCO dealer when selecting an alternate spark plug).

An improper spark plug may have an incorrect fit or
heat range for your engine. This may cause severe en-
gine damage which will not be covered under warranty.
Never use a spark plug with an improper heat range, as
severe engine damage may result.
